Answer
  • Wet sump lubrication system stores the oil in a reservoir inside the engine.

Question 3

Question
Q3. Which of the following statements is incorrect?
Answer
  • Oil absorbs heat from the engine components and dissipates to the atmosphere through a heat exchanger

Answer
  • Wide ratio of uses
  • Wide ratio of temperatures
  • It is specially designed for airplanes
  • It is specially prepared for winter

Question 5

Question
Q5. One of the following statements is vital for aviation (regarding to lubrication system)
Answer
  • It must work properly in every altitude or atmospheric conditions
  • It doesn’t need an element to cool the lubricant
  • Oil leakages are not important
  • None of them are true

Question 6

Question
Q6. Which of these is not part of the lubrication system?
Answer
  • Pressure pump
  • Crankcase
  • Filters
  • Oil tank

Question 7

Question
Q7. Excessive heat in engine operation...
Answer
  • Affects the behavior of the combustion with the possibility of detonations
  • Shortens the life of the engine
  • Impairs lubrication
  • All of them are true

Question 8

Question
Q8. Which of these is a disadvantage of Cowl Flaps?
Answer
  • They control the airflow
  • They increase the performances of the engine
  • They increase drag
  • None of them are disadvantages

Question 9

Question
Q1. A fixed pitch propellers...
Answer
  • A. For a fixed blade angle, variations in TAS (or RPM) implies variation of the angle of attack
  • B. For a fixed blade angle, variations in TAS (or RPM) do not implies variation of the angle of attack
  • C. The propeller can be optimized for several flight conditions
  • D. AandCaretrue

Question 10

Question
Q2. In variable pitch propeller aircrafts...
Answer
  • Pilot uses fine pitch during cruise
  • Pilot uses coarse pitch in take off
  • Pilot uses fine pitch during takeoff because more power is needed
  • All are false

Question 11

Question
Q3. In constant speed propellers...
Answer
  • A. The pitch setting must be modified by the pilot during the flight to maintain a determined constant rotational speed
  • B. The pitch setting varies automatically during the flight to maintain a determined constant rotational speed
  • C. The pilot actuates directly in the governor to control the blade angle variation
  • D. A and C are true

Question 12

Question
Q4. The Constant Speed Unit (CSU) is used in
Answer
  • Piston engines
  • Turboprop
  • Both of them
  • None of them

Question 13

Question
Q5. With a pre-selected RPM, pilot decides to descent
Answer
  • It is an overspeed condition, so flyweights tilt outwards and raise pilot valve which introduces oil to increase propeller pitch and lower engine RPM
  • It is an underspeed condition, so flyweights tilt outwards and raise pilot valve which introduces oil to increase propeller pitch and lower engine RPM
  • It is an underspeed condition, so flyweights tilt inwards and pilot valve is forced down which decreases oil flow to decrease propeller pitch and increase engine RPM
  • None of them

Question 14

Question
Q6. With a pre-selected RPM, pilot decides to ascent
Answer
  • It is an overspeed condition, so flyweights tilt outwards and raise pilot valve which introduces oil to increase propeller pitch and lower engine RPM
  • It is an underspeed condition, so flyweights tilt outwards and raise pilot valve which introduces oil to increase propeller pitch and lower engine RPM
  • It is an underspeed condition, so flyweights tilt inwards and pilot valve is forced down which decreases oil flow to decrease propeller pitch and increase engine RPM
  • None of them

Question 15

Question
Q7. Regarding to icing in blades...
Answer
  • A. A good propeller de-icing could be resistance heating elements
  • B. It causes aerodynamic shape lost
  • C. Due to the propeller's high spin velocity, icing in blades is not common
  • D. A and B are true

Question 16

Question
Q8. Regarding to propellers
Answer
  • A. Propellers are better propellants than jet engines
  • B. Propellers are worse propellants than jet engines
  • C. Propellers are not good a high cruising speed due to excessive velocities in blade's tips
  • D. A and C are true

Question 17

Question
Q1. Which was the first jet-powered aircraft?
Answer
  • Spitfire
  • Junkers Ju 87
  • Bell P-59
  • Heinkel He-178

Question 18

Question
Q2. Why was the aircraft Gloster Meteor so popular?
Answer
  • It was the first jet-powered aircraft.
  • It was the first aircraft to break the sound barrier.
  • It was the first aircraft with sufficient speed to attack the German V1 flying bomb.
  • It was the first aircraft that could perform sustained inverted flight.

Question 19

Question
Q3. The engine Jumbo 004B was a milestone in the turbojet engine because...
Answer
  • It had the first axial compressor in a turbojet engine.
  • It had the biggest change of pressure in one stage up until then.
  • It was the most produced engine in the WWII.
  • All the answers are false.

Question 20

Question
Q4. Mark the right answer:
Answer
  • A turboprop produces more impulse than a turbojet.
  • A low-BPR turbofan has a bigger SFC than a high-BPR turbofan in low speeds.
